To assess long term effectiveness of Instrument assisted soft tissue mobilization, Physio gun and Foam roller on Quadratus lumborum muscle flexibility, lumbar spine range of motion and functional status of subjects with chronic low back pain - A comparative interventional study

There are various treatments that can be used to relieve Quadratus Lumborum (QL) muscle tightness, these treatments include stretching, muscle energy technique (MET), myofascial release therapy (MFR), positional release therapy (PRT), transverse friction massage (TFM). instrument assisted soft tissue mobilization, physio gun and foam roller are forms of myofascial release improves muscle flexibility and fascial restriction. Incorporating these tools for improving QL flexibility will help to improve lumbar spine mobility and overall functional ability. These tools are easy to use as they reduce imposed stress on the hands of a therapist, also can be used as home-based intervention and for self-care.

This study will highlight the importance of targeting Quadratus Lumborum muscle and including this muscle in the treatment of LBP as it is involved as a potential source of low back pain.

It will emphasize the significance of addressing Quadratus Lumborum muscle in the management of low back pain (LBP) also to evaluate the effect of Instrument assisted soft tissue mobilization, physio gun and foam roller on QL muscle flexibility, lumbar spine range of motion, functional ability and to compare the effect of each technique and determine which is more effective in the treatment of LBP.
